Product Description

*** You Cannot Just Install a Metal Gear Without Also Changing The Motor To The GruvenParts INTERNALLY GROUNDED MOTOR !  You Will Short Out the Body Control Module.  All Of Our Kits Come With New Motors Which Are Internally Grounded and Work With Metal Gears - So Don't Just Replace the Gear, You Must Replace Both Gear AND Motor When Going to Metal !!! ***



 ** Click HERE for the NEW GruvenParts Installation Video **

** Click HERE for the Mirror Gear DIY Article for Full Size GM Trucks **  or (Download PDF)

** Click HERE for the Traverse/Acadia/Outlook Supplemental Instructions **


** 3 Options Are Now Available ***

Option 1: 

Buy strengthened brass gears + hi-torque motors in quantity of 1 set for 1 mirror or 2  sets for both mirrors ($49.99 / $89.99). Requires 24 hour epoxy of brass gear onto main shaft in your unit.  You will re-use your existing main shaft and epoxy on a new brass gear section.


Option 2:

Buy strengthened brass gears pre-mounted to a new machined steel main spiral shaft + hi-torque motor in quantity 1 set for 1 mirror or 2 sets for 2 mirrors ($64.99 / $99.99).  Does not require any epoxy cure time to install, its plug and play.


Option 3:

Buy a rebuilt complete motor drive unit with new hi-torque motor and brass gear pre-installed and tested ($229.99 minus $30 core return = $199.99).  Please note when buying the complete drive unit, you must choose passenger side or drivers side, and there is a $30 core refund so be sure to send back your old assembly in repairable condition.  Core returns are only applicable to complete drive units and when you are ready to return your core, please email for instructions.  Your CORE must be rebuildable.  We cannot accept units which have parts other than the motor/spur gear broken as cores as we would have no way to rebuild them.


Other Parts Available :

We also carry a limited number of used parts to service these mirrors in case you loose or break something.  We have some of everything, so just email if you need something.  We do now have some used mirror glass drive units for both sides - these are the little motorized units that actually adjust the angle of the mirror glass.


** Product Description ** is pleased to announce replacement strengthened BRASS spur gears and high torque INTERNALLY GROUNDED motors (OEM MOTOR WONT WORK WITH METAL) for the power folding mirrors on 2007-2014 GM trucks including Acadia, Traverse, Enclave, Escalade, Silverado, Avalanche, Tahoe, Suburban, Sierra, Yukon, and Denali.  Also fits ALL 2007-Present GMC pick-up trucks. As many have discovered, the folding mirror assembly on these trucks suffers from a thin, weak, plastic spur gear mounted to the main drive shaft.  The plastic spur gear cracks at the slightest impact or just wears out over time causing an inoperable folding mirror.  The GM motors also get weak and die quickly. Unfortunately, GM will only sell you a complete folding mirror assembly, which will cost you from $700-$1,200 ea after labor and paint, depending on the year/make/model.  And that $ would be wasted on another mirror assembly with another weak, plastic spur gear and weak electric motor that will also soon fail.  Don't waste time or hard earned money on more GM parts that will also soon fail! has addressed this issue by designing a strengthened spur gear made from solid gear BRASS with a thicker cross section to eliminate the stress concentrations which cause fatigue cracking in the GM plastic gear. We have also designed a replacement high torque electric motor to accompany this new metal gear. Our new electric motor is required when switching out to the metal gear, as the ground circuit in the OEM motor does not allow for a metal gear to be installed. You can buy the gear/motor combo for one of both sides, and with the spur gear pre-attached to a new main shaft, or loose. Loose gear orders require installation of the spur gear onto the main shaft using 24 hour epoxy - please refer to the DIY article link above.  We have thoroughly tested our redesigned spur gear and high torque motor using a new, OEM mirror assembly and computerized test equipment.  Our test samples barely showed any wear whatsoever, and the testing did include random wacks against the mirror, jamming the mirror operation as it was folding, and manually stressing the mechanism all in an attempt the break the gear.  Each sample was tested more than 5,000 open/close cycles and was still going strong at that point !  

This product carries a LIFETIME WARRANTY!  Provided you don't burn the vehicle, or otherwise smash the mirror into something, you can send back the motor drive unit to us and we'll replace the gear assembly and get it working again free of charge.  You would only be responsible for shipping under this warranty.

  2. Excellent Mirror Fold Motor Assembly for 2008 Buick Enclave 5 Star Review

    Posted by on 17th Oct 2020

    MY original drivers side motor became erratic and eventually died completely. The dealer wanted $800 to replace the whole side mirror claiming motors were not individually available. I found a reference to Gruven in a Buick owners forum which included complete instructions. I did a trial disassembly of my mirror and verified the motor was accessible without removing the mirror assembly from the door. I ordered the whole fold motor assembly because I wanted a plug and play solution. When the motor arrived it took less than 30 minutes to complete the job. No hassle, no painting, and my mirror is now folding perfectly. Thank you Gruven for saving me $600.

  3. Well Done 5 Star Review

    Posted by on 16th Oct 2020

    I was skeptical about the cost however, when I got to doing the change on my Denali the youtube instructions made it simple. Following directions, I was done in about an hour and saved over $230.00 vs. a replacement mirror assembly that did not have the auto darkening the original mirror has.

  4. Love it! 5 Star Review

    Posted by on 7th Oct 2020

    I’ve installed these on both GMCs that I own. The factory ones are crap and didn’t last long given that I use them everyday in and out of my garage. The aftermarket kits have worked flawlessly for years! Great installation directions and walkthroughs.

  5. Great product that whould have been OEM! 5 Star Review

    Posted by on 5th Oct 2020

    Worked great to repair my broken mirror gear. I bought the gear pre-glued to the motor which saved some time, but wish I had just bought the whole assembly to save more time. I'm very mechanically inclined and work on all my cars but it was tricky to r&r the motor assembly, not terrible but time consuming. Thanks for offering great solutions for these vehicles!

  6. Exactly what I needed 5 Star Review

    Posted by on 2nd Oct 2020

    Thanks for providing an excellent replacement part!

    I repaired my driver side mirror yesterday and very pleased to report it works well with Gruven Parts. I had to repair the passenger side 3 years ago. Nice option to buy the pre-attached gear this time. I highly recommend

  8. Folding Mirror Repair 2011 Avalanche 5 Star Review

    Posted by on 28th Sep 2020

    Purchased the set for right and left folding mirrors on a 2011 Avalanche. The parts were a direct fit replacement and operate at a faster pace when folding the mirrors in or out. Extremely cost effective and a quality product! Installed these myself one year ago and they are working great with no issues so far. Definitely recommend this product.

  10. great product. Happy I found them 5 Star Review

    Posted by on 23rd Sep 2020

    I was watching videos on how to repair the folding mirrors, The first one was ok but then there video came on.much better than the first one I watched , Better detail and to mark the way it came apart to make reasemably easer. As am a Heavy Duty Mechanic by trade and at the end of the video they said they sold metal gearing.I was sold right then and there. I did not get a return e-mail so I E-mailed them , Then I got a phone call from them, turned out my e-mail box was full. Thank to Paul for the phone call. Am still waiting for the parts to show up. Thanks again. Ken
